Long time reader.. first time poster.
I've created a free web service that helps add Push to your app quickly and easily (and it manages all communications with apple as well). It is completely operational -- just working on pretties now.
I'd love feedback:
iPhonePusher - Home
The basic idea is that you can leverage all of your customers when a new product comes out or you start a sale. The site allows you to broadcast a message to them via Push. For instance, if 5000 people have downloaded your lite version, you can push a message to their phone telling them that the full version is on sale for this week. Their phone buzzes in their pocket, and your message appears front and center on their phone.
I haven't worked out future monetization schemes, so if anybody has opinions, I'd love to here them.
